NEET Physics Newton's Law of Cooling MCQ Question

Type: MCQ-numerical-Hard-Class 11

A hot object at temperature T_2 is placed in a large room with a constant temperature T_1. According to Newton's Law of Cooling, which of the following expressions represents the rate of cooling of the object?

A

-k(T_2 - T_1)

B

k(T_2 + T_1)

C

-kT_2

D

kT_1

Correct Answer

Option A

Detailed Explanation

Newton's Law of Cooling states that the rate of cooling is proportional to the excess temperature of the body over the surroundings, represented as -k(T_2 - T_1), where k is a positive constant.
